Digital Bend Angle Measuring Device

The AM150 digital protractor uses two arms to measure a bend angle. One arm is fixed and the other arm (dynamic) has two axis of motion. The dynamic arm has both rotational and linear motion. The rotational motion is guided by sealed roller bearings and the linear motion is guided by a linear ball bearing. These combined motions allow the AM150 digital protractor to move quickly from one bend configuration to another while at the same time providing sensitivity for accurate measuring. Patented.
